Formula
For single-phase:
For three-phase:
Where:
- C = Capacitance in microfarads (µF / MFD)
- kVAR = Reactive power
- f = Frequency (Hz)
- V = Voltage (Volts)
Example Calculation
Convert 10 kVAR to MFD at 400V, 50Hz (3-phase system)
1. Write formula:
C = (10 × 109) / (2 × 3.1416 × 50 × 400² × 3)
2. Calculate denominator:
400² = 160,000
2 × 3.1416 × 50 × 160,000 × 3 =
150,796,447 (approx)
3. Final calculation:
C = 10,000,000,000 / 150,796,447
C ≈ 66.3
µF
Result: 10 kVAR ≈ 66.3 MFD at 400V, 50Hz (3-phase)

Unit Standardization: SI vs. Imperial Sizing in kvar to mfd calculator
When working with kvar to mfd calculator calculations, using consistent physical units is vital. Small translation errors between SI Metric units (like millimeters, kilowatts, and meters) and Imperial units (like AWG wire, horsepower, and feet) can lead to serious sizing errors:
| Dimension | SI Metric Unit | Imperial Unit | Conversion Conversion Factor |
|---|---|---|---|
| Power | Kilowatts (kW) | Horsepower (HP) | 1 kW ≈ 1.341 HP |
| Length | Meters (m) | Feet (ft) | 1 m ≈ 3.2808 ft |
| Flow Rate | Cubic meters/hr (m³/h) | Gallons/minute (GPM) | 1 m³/h ≈ 4.403 GPM |
Always perform unit checks before installing physical components for kvar to mfd calculator to ensure they match equipment specification sheets.
